To all {whom it my concern:

Be it known that I, James RICHARDS, a

citizen of the. United States, residing at Baltimore, State of Maryland,have invented a new and usefulAeroplane', of which the following is aspecification.

This invention relates to aero lanes and more especially to means wherey a quick.

the aviator whereby the twosections can be shifted relative to eachother about a transverse axis, thereby to allow the nose portion of themachine to be pointed upwardly while the remainder of the machine issupported by the running gear on the ground, and facilitating the abruptascent of the machine from a limited area.

With the foregoing and other objects in view which will appear as the;description proceeds, the invention consists of certain novel details ofconstruction and combinations of parts which will be hereinafter morefully described and pointed out in the claims, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the spirit or sacrificing any of theadvantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings- Figure 1 is a view partly in side elevation and partlyin section of the areoplane, one of the positions of the nose portionbeing shown by dotted lines.

Fig. 2 is an enlarged vertical transverse section on line 22, Ifig. 1.

Fig. 3 isa view in diagram showing how the cam operates to shift thenose.

Referring to the. figures by characters of reference, 1 desi ates therear or tall portion of the body of the aeroplane, the same beingprovided with running gear 2 and carrying a rudder 3 which can beoperated in suitable manner, as bv means of foot pedals 4 operating anendless belt 5 engage Specification of Letters ma; P t t d Dee. 16,191.9.

a ear 10 secured to a post 11 having a hand w eel 12. Secured to theshaft 8 so as to rotate therewith are cam arms 13 haying rfctk tgaeth 14and formed in each arm is a. s c 1 The front section 16 of the aeroplaneI body carries the sustaining plane. :17, the

ropeller 18 and the engine, not shown. his section is hingedly connectedat thetop of the rear end thereof to the section 1, as shown at 19.Extending rearwardly from each side of the section 16 is a pairof arms20, the arms of each pair being connected by a pin 21. The arms 20' arelocated at each side of the respective cam arms 13 and the ins 21 areslidably mounted in the slots 15. ournaled between the arms 20 of eachpair is a gear 22 constantly in mesh with t e teeth on the adjacent arm13.

From the foregoing it will be apparent that when the arms 13 are swungdownwardly-they will rotate the gears 22 andthrust therethrough againstthe section 16, causing it to swing upwardly, as indicated by dottedlines, in Fig. 1, so that the rotating propeller will exert an upwardpull upon the aeroplane and cause the machine to move upwardly at anabrupt angle. By reversing the movement of the arms 13 the front section16 will be moved downwardly. (The action of the arms on the nose offront section 16 of the machine has been indicated i in diagram in FiWhat is claim is I 1. The combination with an aeroplane body including arear section, and. a front section hingedly connected to and adapted toswing upwardly and downwardly relative to the rear section, of a cam armmounted for oscillation within the rear sec tion, means on the frontsection for slidably engaging the cam arm, revoluble means on the frontsection for receiving the thrust from the cam arm, and means foractuating the cam arm.

2. The combination connected front and rear sections of an aeroplanebody, of longitudinally slotted cam arms mounted on the rearsect1on,means for with the hingedly,

the front-section for sliding en'gagement ing a wheel 6 on the shaft 7of the rudder; with the arms, n rwi s Ma aw and revohible means on thefront seeti'on'for receiving the thrust from the arms.

3. The combination with hingedly connected frontv and rear sections ofan aeroplane body, of a shaft journaled in the rear section,longitudinally slotted arms conneeted to'the shaft and constitutingcams, each arm having a longitudinal slot, rack teeth upon each arm,gears freely revoluble on the front section and engaged by and adaptedto receive thrust from the toothed arms; and means uiaon the frontsection and projectin into the slots in the arms for holding t e armsand gears in mesh. I

In testimony that I claim the fiorgoing as 15 my own, I have heretoaflixed my signature in the presence of two Witnesses.

JAMES RICHARDS.
